DAC0832产生集中波形，protues仿真通过，非常好的资料-Protues DAC0832 produce concentrated waveform, the simulation through, very good material

用89C51和DAC0832产生正弦、三角、梯形、方波，用按键选择波形输出。附有protues仿真图，keil源程序（汇编），产生正弦波表格的运用程序。-With the 89C51 and the DAC0832 produce sine, triangle, trapezoid, square, with the key option waveform output. With protues simulation map, keil source code (compilation),
